INJECTOR WITH THE SCREW WRAPPER Russian patent published in 2018 - IPC B05B1/34 B05B1/26 

FIELD: devices for spraying liquids.

SUBSTANCE: invention relates to spraying of liquids. Atomizer comprises a housing, a fitting and a coaxially positioned insert-swirler with an external helical thread and an expanding conical opening inside. In the fitting a cylindrical inlet opening is made, connected to a diffuser, which is made axially symmetric in the housing. In the lower part of the body there is an axially symmetric body of the nozzle. Nozzle is made to be two-stage and coaxial to insert-swirler. First stage of the nozzle is a mixing chamber, which is made in the form of a confuser, in series connected to the expanding conical opening made inside the insert-swirler. Mixing chamber can be made cylindrical, in series connected to an expanding conical hole made inside the insert-swirler. Second stage of the nozzle is a continuation of its first stage, made in the form of a diffuser. On the inner conical surface of the diffuser a screw-like thread is made. Diffuser is axially symmetric to the body in the internal cavity of the diffuser. It is made in the form of a screw partition in the form of a conical auger, resting against a perforated partition fixed to the diffuser cut and made in the form of a circle to which the perforated confuser is connected axially symmetrically. Space between the walls of the diffuser and the screw partition is filled with a filler made of fibrous elastic material, for example, a tangled metal wire or plastic chips.

EFFECT: higher quality of spraying liquid, efficiency of the atomizer, reduced hydraulic losses.
